  • With Fewer Than 50 Days to Go Before the Super
    With fewer than 50 days to go before the Super Computing 2004 conference, high-energy physics researchers at the University of Sao Paulo recognized the opportunity to showcase their active involvement in the global computational Grid. They asked the CIARA (Center for Internet Augmented Research and Assessment) team at FIU, and the ANSP (Academic Network of Sao Paulo) team to leverage their expertise, along with AMPATH to create a 2.5 Gigabit per second (Gbps) connection for research from the conference center floor in Pittsburgh, to the computational clusters in Brazil. To do this, a team was formed of Telecom Italia Sparkle's Latin American Nautilus, providing the submarine cable capacity; Cisco Systems, providing critical components for the end-to-end connection; Terremark, providing space and support in their Network Access Points (NAPs) in both MIami and Sao Paulo; FPL Fibernet, providing crucial links in Miami; and Qwest Communications and Internet2's Abilene network, providing high-performance connectivity from Miami to Pittsburgh. The result of this collaboration was a contribution to the winning team of the 2004 bandwidth challenge, allowing them to exceed their goal of 100Gbps. The new link between Miami and Sao Paulo set a new speed record for U.S. to Brazilian research networking at a sustained 1.66Gbps, with bursts up to 2Gbps. This new link increases 45 times the bandwidth capacity between the US and Brazil. This is a first step in bringing research connectivity in the Gigabit range for U.S. to Latin American research efforts.

  • Anatomy of an International Exchange Point: Distributed Network Monitoring Using Monalisa and Netflow1
    Anatomy of an International Exchange Point: Distributed Network Monitoring Using MonALISA and NetFlow1 Ernesto Rubi, Xun Su, Iosif Legrand, Heidi Alvarez, Julio Ibarra2 Abstract: In this paper we present a distributed network monitoring system, which exploits MonALISA (Monitoring Agents in A Large Integrated Services Architecture), a distributed web service delivery infrastructure designed to collect and process the network monitoring information. We augment the capability of MonALISA with FlowTools, the popular NetFlow data analysis toolset. We demonstrate how to integrate MonALISA and Flowtools via an UDP-listening agent ApMon, and highlight a case study of AMPATH, an international exchanging point located in Miami and serving a number of South American National Reseach and Education Networks (NRENs). Our experience showcases the elegant design philosophy of a scalable distributed service deployment platform coupled with the open-source traffic analysis tools and its impact on the daily operation of the production networks. Keywords: NetFlow, MonALISA, Flowtools, Network monitoring. 1. Introduction As the Internet expands both in its scope, reach and capacity, it becomes evident that there is a strong need to develop a distributed network monitoring infrastructure that can be scaled to support various network topology, traffic granularity and user applications. NetFlow[1] is a widely deployed router-based traffic monitoring mechanism. FlowTools[2] is a open-source NetFlow analysis toolset underlying the data gathering and analysis infrastructure of our project. It is our main motivation to effectively use NetFlow to gain crucial understanding of the traffic characteristics of the networks we operate. In particular, we are interested in understanding how to exploit the key advantages and avoid drawbacks of NetFlow-based traffic analysis by augmenting it with a distributed service-deployment platform.

  • World Network Speed Record Shattered
    World Network Speed Record Shattered Caltech, SLAC, Fermilab, CERN, Michigan, Florida, Brookhaven, Vanderbilt and Partners in the UK, Brazil, Korea and Japan Set 131.6 Gigabit Per Second Mark During the SuperComputing 2005 Bandwidth Challenge SEATTLE, WA -- For the third consecutive year, the “High Energy Physics” team of physicists, computer scientists and network engineers led by the California Institute of Technology, the Stanford Linear Accelerator Center (SLAC), Fermilab and CERN and partners at the University of Florida, Vanderbilt and the Brookhaven National Lab, as well as international participants from the UK (University of Manchester, and UKLight), Brazil (Rio de Janeiro State University, UERJ, and the State Universities of São Paulo, USP and UNESP)., Korea (Kyungpook National University, KISTI) and Japan (the KEK Laboratory in Tsukuba) joined forces to set a new world record for data transfer, capturing first prize at the Supercomputing 2005 (SC|05) Bandwidth Challenge (BWC). The HEP team’s demonstration of “Distributed TeraByte Particle Physics Data Sample Analysis" achieved a peak throughput of 151 gigabits per second (Gbps), and an official mark of 131.6 Gbps measured by the BWC judges on 17 of the 22 optical fiber links used by the team, beating their previous mark for peak throughput of 101 Gbps by 50%. The record data transfer speed is equivalent to downloading five full DVD movies per second, or serving 10,000 MPEG2 HDTV movies simultaneously in real time, or transmitting all of the printed content of the Library of Congress in 10 minutes. The team sustained average data rates above the 100 Gbps level for several hours for the first time (as shown in the figure below), and transferred a total of 475 Terabytes of physics data among the team’s sites throughout the US and overseas within 24 hours.

  • Press Release
    PRESS RELEASE Media Contact: Vasilka Chergarova, Research Coordinator Center for Internet Augmented Research and Assessment (CIARA) Florida International University 305-348-4105 [email protected] AtlanticWave-SDX demonstrates its first distributed Software- Defined Exchange controller Miami, Florida, September 29th, 2016 – During the 2016 Global Lambda Integrated Facility meeting, co- located with the 2016 Internet2 Technology Exchange, in Miami, the Georgia Institute of Technology (Georgia Tech) and Florida International University (FIU) demonstrated the first version of the AtlanticWave-Software Defined Exchange (SDX) distributed network controller. Conference participants had the opportunity to interact with the development team, provide feedback and establish new partnerships. The lead software developer, Sean Donovan, presented the challenges of developing an SDX controller to domain scientists and network engineers. These challenges range from identifying switches that support 100GE and OpenFlow 1.3, to interpreting the language of network to domain scientists that may not be familiar with it, to allow network control Application Programming Interface (API) development possible. The AtlanticWave-SDX controller under development will support research, experimental deployments, prototyping and interoperability testing, on national and international scales. During the demonstration, the SDX controller source code was made available [1], and an updated demonstration is planned for the Supercomputing 2016, from November 14-17th, in Salt Lake City, Utah. Russ Clark, Senior Research Scientist at Georgia Tech, also announced that the first prototype would be released before the end of 2016 and production deployments will start early next year, involving three Academic Open Exchange Points: Southern Crossroads (SoX) in Atlanta, AMPATH in Miami and SouthernLight (SoL) in Sao Paulo/Brazil, using the AmLight Software Defined Network (SDN).

Africa offers research and education communities with unique biological, environmental, geological, anthropological and cultural resources. Research challenges in atmospheric and earth sciences, materials sciences, tropical diseases, biology, astronomy and other disciplines will benefit by enhancing the technological and social connections between the research and education communities of the U.S., Brazil / Latin America and Africa. For many years, we have seen the dramatic benefits of high-performance networking in all areas of science and engineering.
